At least on a Mac Audacity seems to have issues when it comes to using third party plugins (i.e. AU or VSTs). To pinpoint which type of plugin is responsible for poor Audacity to crash, you can do the following.
I. Locate Audacity Config File
On a Crapple Mac the
audacity.cfg file should be located here:
II. Open and edit with your favourite text editor
We chose to use BBEdit here, since BareBones kindly provided us with an NFR copy. Edit or add these lines:
III. Pinpointing responsible Plugin Type
Set the Enable switch to true (means
Enable=1) to activate certain plugin types. To disable a plugin type set
Enable=0. In my case above, I enabled all plugin types, but Apple’s AUs.
IV. Final Words.
My experience shows that VSTs plugins are often more stable in comparison to Apple’s AU plugins. So this is not the first time to find out, that the AUs where causing instability.
